This is incorrect. The sender of the SUBSCRIBE will always use:
SUBSCRIBE sip:[EMAIL PROTECTED]
Also, this sender doesn't know if its SUBSCRIBE wil be handled by A's
UA or by a presence server.
Example:
- A calls B:
INVITE sip:[EMAIL PROTECTED]
From: sip:[EMAIL PROTECTED];tag=1234
Call-ID: abcdefg
- B generates this SUBSCRIBE:
SUBSCRIBE sip:[EMAIL PROTECTED] SIP/2.0
From: [EMAIL PROTECTED];tag=xxxxx
To: sip:[EMAIL PROTECTED]
Event: dialog;call-id=abcdefg;to-tag=1234
The SUBSCRIBE sent by B *always* contains the username (A) in the RURI.
